void usbh_ehci_hw_delay_ms (
  U32 ms
);

The usbh_ehci_hw_delay_ms function provides a functionality to the EHCI USB Host controller driver to delay execution for a specified time in milliseconds. This function is used by EHCI USB Host controller driver for hardware specific request that require specific timing, for example for hardware initialization and port resetting.

The usbh_ehci_hw_delay function is part of the RL-USB Host software stack.

You can modify this function to suit different CPU clock settings. This function will need to be changed if EHCI controller is used on a chip that does not yet have a low level driver provided.

None.
